Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a semi-reverse construction formwork structure for an ultra-high closed concrete water storage tank. Background Art

[0002] In the conventional construction of reinforced concrete closed water storage tanks, a set of standard construction procedures are usually followed:

[0003] 1. Foundation excavation to lay a solid foundation for the subsequent construction of the reservoir wall;

[0004] 2. Binding of steel bars for the bottom plate and wall of the water storage tank;

[0005] 3. Formwork and concrete pouring of the bottom plate and pool wall below the construction joint lays an important foundation for the formation of the pool;

[0006] 4. Tie up the steel bars of the top plate and the pool wall above the construction joint;

[0007] 5. Formwork for the top plate and the pool wall above the construction joint;

[0008] 6. Binding and formwork of top plate reinforcement;

[0009] 7. Concrete pouring and capping of the top plate and the pool wall above the construction joint;

[0010] From the above points, it can be seen that in the existing conventional construction of reinforced concrete closed water storage tanks, when the wall of the water storage tank is greater than 5m, it is necessary to divide the wall into multiple layers in the vertical direction for construction, and to carry out the construction from bottom to top in sequence. This means that the erection of the scaffolding needs to run through the entire construction period, and in the conventional construction process, the construction formwork structure needs to be continuously disassembled and assembled. Whether it is the erection of the scaffolding or the construction of the layered sections, it will invisibly lengthen the construction period, and will also increase labor costs and construction costs. In order to improve the defects, it is necessary to propose a semi-reverse construction formwork structure for an ultra-high closed concrete water storage tank. Utility Model Content

[0011] In order to overcome the deficiencies of the existing technology, the utility model provides a semi-reverse construction formwork structure for an ultra-high closed concrete water storage tank, which solves the problem that layered construction prolongs the construction period and increases labor costs and construction costs.

[0012] The technical solution of the utility model is as follows:

[0014] A pool wall reinforcement wall and a pool wall formwork arranged on both sides of the pool wall reinforcement wall are provided in the reserved space of the pool wall, and connecting parts are provided through the pool wall formwork and the pool wall reinforcement wall in sequence, and the connecting parts are used to limit the pool wall formwork, wherein the pool wall formwork is used to shape the poured concrete, and the pool wall reinforcement wall is used to improve the strength of the concrete pool wall.

[0015] In one possible implementation, the pool wall reinforcement wall includes transverse reinforcements and longitudinal reinforcements. The longitudinal reinforcements are arranged at equal intervals along the vertical direction of the pool wall, and the transverse reinforcements are arranged at equal intervals along the horizontal direction of the pool wall. The transverse reinforcements are tied and connected to the longitudinal reinforcements.

[0016] In a possible implementation, the diameter of the transverse steel bars is 6 mm, and the spacing between adjacent transverse steel bars is ≤180 mm.

[0017] In a possible implementation, the diameter of the longitudinal steel bars is 8 mm, and the spacing between adjacent longitudinal steel bars is ≤200 mm.

[0018] In a possible implementation, it also includes auxiliary jacking supports arranged on both sides of the reserved space of the pool wall, the auxiliary jacking supports are located in the main support, one end of the auxiliary jacking supports abuts against the pool wall template, and the other end is connected and fixed to the main support, and the auxiliary jacking supports are used to reinforce the pool wall template.

[0019] In a possible implementation, it also includes reinforcing cross bars arranged on both sides of the reserved space on the pool wall, the reinforcing cross bars are located in the main support, and the reinforcing cross bars are connected and fixed to the main support, and the reinforcing cross bars are used to improve the structural strength of the main support on the side close to the reserved space on the pool wall.

[0020] In a possible implementation, the connecting member is a water-stopping screw, the water-stopping screw is arranged through the steel reinforcement wall of the pool wall, and the two ends of the water-stopping screw are respectively connected to the pool wall formwork on both sides.

[0021] The beneficial effect of the utility model according to the above scheme is that a semi-reverse construction formwork structure for an ultra-high closed concrete water tank includes a main support with a height greater than 5m, a reserved space on the pool wall, a pool wall steel wall, a pool wall formwork and connecting parts. By setting up the main support and arranging the pool wall formwork and the pool wall steel wall in the reserved space on the pool wall, the pool wall and top plate of the water tank with a height of more than 5 meters can be cast at one time. Compared with the traditional construction method using layered sections, the formwork structure of the utility model can greatly shorten the construction period, thereby reducing the labor cost of construction, and thus reducing the overall cost of construction as a whole.

[0027] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0028] It should be noted that when using traditional reinforced concrete closed water tanks to construct a water tank wall with a height greater than 5m, it is necessary to construct the water tank wall in layers from bottom to top, and the low-height sections need to be removed after construction is completed. The higher-level sections of the water tank wall must be supported, tied and poured, and moved upward in sequence. Therefore, the use of this layered water tank wall construction method invisibly increases the construction period and increases the construction cost. For this reason, the present application proposes a semi-reverse construction support formwork structure for an ultra-high closed concrete water tank to improve the above-mentioned defects.

[0029] like Figures 1 to 3 As shown, a semi-reverse construction formwork structure for an ultra-high closed concrete water storage tank comprises a main support, wherein the main support is provided with a pool wall reserved space for pouring the pool wall structure, and the height of the main support is at least 5m; wherein, the pool wall reserved space is provided with a pool wall steel bar wall, and a pool wall formwork arranged on both sides of the pool wall steel bar wall, and connecting pieces are sequentially arranged through the pool wall formwork and the pool wall steel bar wall, and the connecting pieces are used to limit the pool wall formwork, wherein the pool wall formwork is used to shape the poured concrete, and the pool wall steel bar wall is used to increase the strength of the concrete pool wall.

[0030] In this embodiment, the main support is erected on the upper end surface of the hardened foundation, and a pool wall reserved space for pouring the pool wall structure is reserved in the middle of the main support. The reserved space is used to build the pool wall of the water storage tank, and the upper end surface of the main support forms an operating platform. The operating platform is used to store materials required for building the pool wall. Among them, the structural setting of the operating platform can make it easier for workers to lift construction materials from the operating platform to the pool wall reserved space from top to bottom. Compared with traditional construction methods, the setting of the operating platform can improve the efficiency of workers in transporting construction materials. Specifically, a pool wall steel bar wall formed by steel bars is provided in the pool wall reserved space. The lower end of the pool wall steel bar wall is in contact with the hardened foundation, and the upper end is suspended on the operating platform. Corresponding height, in addition, pool wall formworks are provided on both sides of the pool wall steel wall, the lower end of the pool wall formworks is abutted against the hardened foundation, the upper end face is abutted against the lower end face of the operating platform, and the inner side spacing of the pool wall formworks on both sides is equal to the width of the pool wall, wherein the connecting parts successively penetrate the pool wall formworks, the pool wall steel wall and the pool wall formworks on one side, and the two ends of the connecting parts are respectively connected and fixed to the pool wall formworks on both sides, and further specifically, the pool wall formworks are used to drain the concrete poured into the pool wall steel wall, thereby shaping the poured liquid concrete, avoiding the width of the concrete after solidification being greater than the wide end of the pool wall designed on the drawing, wherein the connecting parts are used to limit the pool wall formworks on both sides, and the pool wall steel wall is used to improve the structural strength of the pool wall. Therefore, the utility model sets up the main support and arranges the pool wall formwork and the pool wall steel wall in the reserved space of the pool wall, so that the pool wall and top plate of the water storage tank with a height of more than 5 meters can be cast at one time. Compared with the traditional construction method using layered sections, the formwork structure of the utility model can greatly shorten the construction period, thereby reducing the labor cost of construction, and thus reducing the overall cost of construction as a whole.

[0033] For further reference, Figure 2 The diameter of the longitudinal steel bars is 8 mm, and the spacing between adjacent longitudinal steel bars is ≤ 200 mm.

[0034] In this embodiment, one end of the longitudinal steel bar is perpendicular to the hardened foundation, and the other end is suspended at the height of the operating platform, and the longitudinal steel bars are divided into two rows and arranged on both inner sides of the reserved space of the pool wall. The spacing between adjacent longitudinal steel bars in the same row is 200 mm. In addition, both rows of longitudinal steel bars are provided with transverse steel bars, and the transverse steel bars are arranged at equal intervals from bottom to top in the vertical direction. The spacing between adjacent transverse steel bars in the same row is 180 mm. In addition, the transverse steel bars are tied and connected to the longitudinal steel bars to form a pool wall steel bar wall that can improve the strength of the concrete pool wall.

[0035] For further reference, Figure 1-3 , and also includes auxiliary jacking supports arranged on both sides of the reserved space of the pool wall, the auxiliary jacking supports are located in the main support, one end of the auxiliary jacking supports abuts against the pool wall template, and the other end is connected and fixed to the main support, and the auxiliary jacking supports are used to reinforce the pool wall template.

[0036] In this embodiment, a number of auxiliary jacking supports are provided on both sides of the reserved space of the pool wall, one end of the auxiliary jacking supports is abutted against the outer side of the pool wall template, and the other end is fixed to the main support by a snap connection. Specifically, the auxiliary jacking supports are arranged in a rectangular row on the vertical plane, so that the main support and the pool wall template are connected into a whole, and then the stability of the pool wall template on both sides is improved through the structural setting of the auxiliary jacking supports.
